Ariana Grande pays tribute to Mac Miller in the lyrics to her hit "Thank U, Next."

Wish I could say, "Thank you" to Malcolm
'Cause he was an angel," she sings.

Grande's tour took her to Mac's hometown of Pittsburgh last night. When she performed "Thank You, Next" she choked up before Miller's name and the crowd helped her with the lyrics.

Miller ODed last September. He had been in a relationship with Grande between 2016 and May of 2018.
